FYI: Just thought this was interesting... perpendicular because there is no
interaction at right
angles???

"The scientists observed static, nanoscale arrangements of electrons measuring
about eight times the
distance between individual iron atoms, all aligned along one crystal axis
reminiscent of the way
molecules spatially order in a liquid crystal display. They also found that the
electrons that are
free to travel through the material do so in a direction ***perpendicular*** to
these aligned
'electronic liquid crystal' states. This indicates that the electrons carrying
the current are
distinct from those apparently aligned in the electronic liquid crystals."
